Abstract
A method for communicating in an advanced long term evolution (LTE-A) network using common reference signal (CRS) resources associated with different interference levels due to resource partitioning is disclosed. Signals are received from an eNodeB indicating a subset of CRS resources for radio link monitoring (RLM) and/or reference signal received power (RSRP) measuring. The subset of CRS resources includes the CRS resources expected to have lower interference from the interfering eNodeBs. RLM and/or RSRP measurements are performed based on the indicated subset.
Claims8
A method for communicating in an advanced long term evolution (LTE-A) network, comprising:
- receiving physical downlink control channel (PDCCH) information in subframes of the LTE-A network;
- determining a block error rate (BLER) for the received PDCCH;
- and
- estimating a radio link quality, from the determined BLER, for radio link monitoring (RLM).
The method of claim 3, in which determining the block error rate comprises determining a hypothetical block error rate for a hypothetical PDCCH by translating the block error rate of the received PDCCH from at least one of a first DCI format, a first aggregation level, and a first resource element (RE) energy ratio to at least one of a second DCI format, a second aggregation level, and a second resource element (RE) energy ratio before estimating the radio link quality.
A apparatus for wireless communication, comprising:
- means receiving physical downlink control channel (PDCCH) information in subframes of a LTE-A network;
- means for determining a block error rate (BLER) for the received PDCCH;
- and
- means for estimating a radio link quality, from the determined BLER, for radio link monitoring (RLM).
A computer program product for wireless communication in a wireless network, comprising:
- a computer-readable medium having non-transitory program code recorded thereon, the program code comprising:
- program code to receive physical downlink control channel (PDCCH) information in subframes of a LTE-A network;
- program code to determine a block error rate (BLER) for the received PDCCH;
- and
- program code to estimate a radio link quality, from the determined BLER, for radio link monitoring (RLM).
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to receive physical downlink control channel (PDCCH) information in subframes of a LTE-A network;
- to determine a block error rate (BLER) for the received PDCCH;
- and
- to estimate a radio link quality, from the determined BLER, for radio link monitoring (RLM).
